• Original OEM BRP publication (P/N MMR2007-002).
• Details TRA III drive pulleys, SC-4 rear suspensions, DPM manifolds, HPG shock absorbers, and VM/TM carburetors.
• Explains Power TEK management, Semi-Direct Injection (SDI), Rotax Electronic Reverse (RER), Digitally Encoded Security System (DESS), and B.U.D.S. diagnostics.
• Includes 38 exploded-view diagrams and 14 diagnostic flow charts for engine and electrical troubleshooting.
• Provided as a 680-page PDF reference set, formatted for standard letter and A4 printing.

Engine and Chassis Documentation

This 2007 first-edition manual serves as the primary factory reference for the complete REV chassis range. It outlines the technical framework required to maintain and troubleshoot the Rotax engine series. The contents detail procedures for the 550, 593, 793, and 797 engine platforms, covering top-end assembly, bottom-end configuration, and the specific cooling requirements for both fan- and liquid-cooled units.

When servicing the 593 or 793 engine platforms, mechanics must be aware of typical repair traps like delaminating carburetor intake boots, which can introduce unmetered air and cause severe lean-condition piston seizures. Furthermore, on SDI-equipped models, technicians should watch for micro-corrosion inside the R1 and R2 power relays; this hidden electrical issue frequently mimics a failing electric fuel pump and leads to unnecessary parts replacement.

You will find clear overviews of exhaust systems, fuel delivery setups, and RAVE valve adjustments, alongside specific inspection parameters for crankshafts, pistons, and reed valve assemblies. The guide also outlines step-by-step procedures for complex tasks that typically require a costly dealership visit, such as executing a closed throttle reset (TPS), overhauling TRA clutches, and servicing HPG shock absorbers.

Specification and Diagnostic Preview

Inside, the documentation provides tightening torque tables categorized by fastener grade (5.8 through 12.9) and size (M4 to M14). It also outlines engine leak verification protocols, utilizing a 34 kPa (5 PSI) pressure threshold to help identify potential seal or gasket defects. To further assist with accurate fault isolation, the reference contains specific visual aids like the engine leak verification flow chart, fuel delivery system diagnostic flow charts, EMS fault code tables, and the ignition system testing sequence.

Having direct access to accurate factory baselines—such as precise W, X, and Z measurements for pulley alignment or specific stator trigger coil resistance values—prevents the common shop bottleneck of misdiagnosing sensor faults, significantly reducing diagnostic bay time per vehicle. Properly navigating factory workshop documentation is essential for technicians to correctly interpret B.U.D.S. software diagnostic codes and wiring diagrams for fuel injection and electrical management systems.

Maintenance intervals are clearly charted for critical components like drive belts, chaincase oil, and suspension linkages. Please note that working on high-performance snowmobiles involves inherent risks; always ensure you have the proper tools, protective gear, and a safe workspace before applying any technical specifications.

This official 680-page BRP shop manual covers the 2007 Ski-Doo REV Series lineup, documenting engine, chassis, electrical, and fuel-injection specifications. It serves purely as a contents overview and reference guide, rather than a step-by-step repair tutorial.
